"Vocal cord dysfunction (VCD) is a condition characterized by paradoxical vocal fold motion with inspiration leading to stridor, air hunger, tachypnea, chest tightness, and a feeling of suffocation [1-3]. A number of different triggers for VCD have been identified since the condition was first described in 1974. Initially, this was thought to be a purely psychiatric condition that was a form of conversion disorder, initially termed “Munchausen’s Stridor” by Patterson et al [4]. While many patients with VCD do carry psychiatric diagnoses, exercise, irritants (reflux of gastric contents, upper respiratory infections, post-nasal drip), and asthma have been identified as other triggers [2]. The interplay of asthma and VCD has been difficult to establish. Estimates of concomitant asthma diagnoses range from one third to one half of all patients with VCD, however it is common for patients with VCD to be completely misdiagnosed – often for years – as having refractory asthma [2,5,6]..."
